Abstract: Approaches herein decrease nanosheet gate length variations by implanting a gate layer material with ions prior to etching. A method may include forming a dummy gate structure over a nanosheet stack, the dummy gate structure including a hardmask atop a gate material layer, and removing a portion of the hardmask to expose a first area and a second area of the gate material layer. The method may further include implanting the dummy gate structure to modify the first and second areas of the gate material layer, and etching the first and second areas of the gate material layer to form a treated layer along a sidewall of a third area of the gate material layer, wherein the third area is beneath the hardmask.

Abstract: A pea-derived peptide with a muscle-building effect and a preparation method thereof, and a drug and use, are disclosed. A pea protein is subjected to enzymatic hydrolysis, and five polypeptides with muscle-building effect are obtained by separation as separate peptide fragments. In an in vitro aging skeletal muscle cell assay, changes are analyzed in a gene expression level of regulatory pathways related to skeletal muscle cell proliferation and differentiation, apoptosis and autophagy, and protein synthesis and degradation. In addition, animal experiments are conducted to study the muscle-building effect and a corresponding mechanism of the pea-derived peptide. This shows that the five polypeptide sequences have a significant muscle-building effect, usable as a polypeptide drug for the treatment of sarcopenia.

Abstract: The embodiment of the present disclosure discloses a method, an electronic device, and a storage medium for a ship route optimization. The method for the ship route optimization considers a dynamic feature of a multi-functional emergency rescue ship and an interference effect caused by an airflow, uses a movement model with kinematics non-holonomic constraints, such as a ship total cost assessment function to simulate the movement of the ship, and based on a sparrow search algorithm, learns how to apply the algorithm to a route plan of the emergency rescue ship. The method can improve the ship route optimization algorithm, improve an accuracy and practical applicability of a calculated plan. The method can effectively and accurately locate obstacles and hidden reefs, and consider effects of an airflow and a non-holonomic constraint effect, so as to make the route planning of the ship more efficient and intelligent.
